“…Piper and Boote [59] showed variation in protein and fat concentration in 20 soybean cultivars, with protein content significantly dependent only on cultivar, while fat content on cultivar and temperature related to latitude. Further, other authors proved significant effect of genotype on protein [54], fat [55,60,61], ash [61], and carbohydrate (raffinose and stachyose) contents [62]. The results presented in this study showed little anecdotal varietal variation in sugar content, which is consistent with the study of Alsajri et al [55].…”

The objective of the study was to evaluate the effect of cold stress at flowering stage on plant structure, yield and chemical composition of seeds of 15 soybean cultivars. The study was conducted in 2019–2020, using the complete randomization method, in three replications. Fifteen soybean cultivars belonging to three maturity groups: early (EC), middle-early (MC) and late (LC) cultivars were included. Weekly cold stress (17/13 °C day/night) was applied at plant flowering stage. In the control treatment, plants were kept under natural conditions (24/17 °C day/night). Our research showed that cold stress negatively influenced the elements of plant structure: height, number of nodes, stem dry mass, number and weight of pods, number and weight of seeds per plant, as well as yield of soybean seeds, reducing it on average by 24%, as compared to the control treatment. The highest yield decrease was found in LC cultivars (31.2%), while a smaller and similar one in EC and MC cultivars (by 19.7 and 20.1%, respectively). Significant varietal differences were found for plant biometric traits and seed yield. EC cultivars had the lowest set first pod, as well as the lowest number of nodes, number of pods and seeds, pod and seed weight per plant, and seed yield. MC cultivars had the highest set first pod, and the smallest stem DM and seed yield average by 29.2% higher compared to EC cultivars. LC cultivars had the highest stem DM, number of pods and seeds, and pod and seed weight per plant compared to the other cultivar groups, and yield by 22.8% higher compared to EC cultivars. The experimental factors significantly affected crude protein, crude fat, and crude ash content, while they did not differentiate water-soluble carbohydrate and crude fiber content. Cold stress at the flowering stage caused a significant increase in protein content (by 4.1% on average) and ash content (by 3.8%) and a decrease in fat concentration (by 6.9%) in soybean seeds. Differences in nutrient content among cultivars were a genetic trait not related to cultivar maturity.

“…The CV for oil content (1.63%) and protein content (1.56%) were of low magnitude indicating a higher experimental precision (Table 2). Nascimento et al (2010) observed CVs of 6.9 and 2.7% for oil and protein contents, respectively, in fifteen soybean cultivars. Although some authors have reported lower yields in off-season cultivated soybeans, the average grain yield of the UFUS soybean lines (2,698 kg/ha) at the four sites was similar to the national average (2,816 kg/ha) for the 2007/08 growing season.…”

“…During the final stages of evaluation and recommendation of cultivars for breeding programs, the study of adaptability and stability is essential to guide the breeder in the selection of the most appropriate genotypes (Cruz et al, 2012). Considering oil and protein traits in soybean, Nascimento et al (2010) emphasized the difficulty of recommending genotypes for different regions due to the paucity of studies of these characteristics under Brazilian conditions.…”

ABSTRACT. The oil and protein contents of soybean grains are important quantitative traits for use in breeding. However, few breeding programs perform selection based on these traits in different environments. This study assessed the adaptability and stability of 14 elite early soybean breeding lines in off-season cultivation with respect to yield, and oil and protein contents. A range of statistical methods was applied and these analyses indicated that for off-season cultivation, the lines UFUS 5 and UFUS 10 could be recommended due to their superior performance in grain yield, oil content, and specific adaptability to unfavorable environments along with high stability in these characteristics. Also recommended were UFUS 06, which demonstrated superior performance in all three tested characteristics and showed adaptation to favorable environments, and UFUS 13, which showed high adaptability and stability and a superior performance for protein content.

“…Analysis of the variance of the mixed model for oil content in soybean genotypes indicates high statistical significance (p <0.01) of the effects of genotypes, environment and their interaction (Table 6). Environmental influence was predominant over influence of genotype and interaction G × E.Although oil content is a genetically determined trait and is considered a varietal characteristic, only 50% of the total variation in seed composition is the result of genotype (BRUMM and HURBURGH, 2002), while the rest of the variability is attributed to environmental factors, primarily temperature and humidity, as well as the interaction of genetic and agroecological factors (VOLLMANN et al, 2000a;NASCIMENTO et al, 2010;LAKIĆ et al, 2019;POPOVIĆ et al, 2013;. content of genotypes tested at the same location in different years were greater than the differences found in genotypes tested in the same year at different locations.…”

Stability of yield and seed composition in early maturing soybean genotypes assessed by AMMI analysis

Identification of stable sources for breeding for important agronomic traits is prerequisite for providing a continuous and long-term progress in breeding. In this study, thirty-one early-maturing genotypes from soybean collection of Maize Research Institute ?Zemun Polje? were evaluated across four environments (two years and two locations) according to randomized complete block design with three replications. The aim of research was to examine the value of the interaction of genotype and environment for three important agronomic traits (seed yield, protein content and oil content) using anadditive main effects and multiplicative interaction (AMMI) statistical model, and to identify stable sources for breeding for listed traits. The results of the research indicated that all traits were strongly influenced by environmental factors, while the influence of genotype and particularly interaction of genotype and environment was of less importance. AMMI analysis enabled identification of genotypes with above average value and high stability for seed yield (three genotypes), protein content (three genotypes) and oil content (two genotypes), which could be utilized as potential stable sources of variability in future soybean breeding programs.
